I think the gold standard is pretty much
Spicyryan's DRG guide when it comes to what's optimal. There isn't really anything he's overlooked and his findings are all based on spreadsheets, not theory.
Ptero +3's jump bonus falls decently behind the Vishap +3 in terms of DPS. Interms of Jumps, STP is king, not damage. Remember jumps are just a tool to help you WS faster or harder. Your Soul jump should be brining you to 3k TP 99% of the time.
There are a few pieces which shouldn't be in your jump set. Ptero +3 instead of Vishap +3, no Vishap +3 gloves, Windbuffet belt instead of Ioheska +1, Valorous greaves instead of Flamma +2 or Ostro (Ostro beats out Flamma +2 because of the STP+). On most fights you should be using Petrov instead of Flamma ring.
It's weird that you have all this omen gear, Ptero +3, but no Vishap +3. I've run DRG on every boss in Omen except Kei so getting cards shouldn't be a problem. Our native high -DT options and excellent hate management make us extremely good in Omen.
